POLE-RING- zvc. 825,762.

Specification of Letters Patent.

Patented July 10, 1906.

Application filed March 26, 1906- Serial No. 308,063.

1'0 all whom it may concern.-

Be it known that I, DICKRAN M. SARKISIAN, a citizen of the UnitedStates, residing in Malden, Middlesex county, Massachusetts, haveinvented certain new and useful Improvements in Pole-Rings, of which thefollowing is a specification.

This invention relates to the class of rings used on curtain-poles, orpoles used for portieres and the like, to support the curtain orportiere, and particularly to such rings when provided with rollers toroll on the pole, and thus reduce the friction; and the main object ofthe invention is to provide an improved mounting for the rollers on therings, as will be hereinafter described with reference to theaccompanying drawings.

In said drawings, Figure 1 is a side elevation of a ring embodying theinvention, the ring being partly in section in order toillustrate theconstruction. Figs. 2, 3, and 4 are detail views on a larger scale.Figs. 5, 6, 7, and 8 are similar views to the first four figures,illustrating a slightly-modified form of the invention. Figs. 9 and 10are enlarged views of one of the rollers and its journal.

Referring to the first four figures of the drawings, 1 designates themain body or sec tion of the tubular ring, constituting aboutthree-fourths of a complete circle, the remainder being made up of asection formed of thick wire 2, upon which are rotatively mounted thewheels 3.

The novel features of the present invention reside mainly in the meansfor securing the ends of the solid section 2 in the open ends of themain hollow section or portion 1 of the ring. On the end of the wire 2is screwed a disk nut 4, of which Fig. 2 is a diametrical section andFig. 3 a face view. This disk nut has in its face a deep groove 5 toreceive the end of the tubular section 1, and when the said nut andtubular section are fitted together they are secured to each other by acircumferential indentation 6, seen best, perhaps, in the sectionaldetail view, Fig. 4. This view shows how, in forming the indentation,the metal of the parts is so pressed in as to form a secure fastening.

The construction of Figs. 5 to 8 is substantially the same as thatdescribed, differing only in the attaching device or nut. Instead ofbeing grooved to receive the end of the tubular part 1, this nut is madein two parts namely, the nut proper, 4 which fits snugly inside thetubular part 1, and a cap 4, which fits over the latter. In Fig. 6 thenut 4 is seen in section, in Fig. 7 the cap 4 is seen in section, and inFig.8 the parts are seen in section, assembled, and secured together bya circumferential indentation 6.

It may be explained that the wheels 3 turn loosely or freely on thesolid section or j our nal 2, being slipped onto the respective ends ofthe latter before it is mounted in the ring 1. To prevent the wheelsfrom sliding along the section 2, the latter may have projections 7, setup with a punch. Fig. 9 shows the wheel 3 in diametrical section, andFig. 10 shows the same in side elevation, detached. It will be notedthat the means or device for securing the solid section 2 to the hollowsection 1 is practically the same in Figs. 4 and '8. The only differenceis that in Fig. 4 the parts are integral and in Fig. 8 they are not. Inboth, however, there is a cylindrical groove or recess to receive theend of the tube forming the section 1. of the ring, and acircumferential clench 6 to secure together the tubular section 1 andthe securing device for the solid section 2 of the ring. Thisconstruction provides a solid journal for the bearingwheels 3 to rotateon. Obviously the ends of the solid section 2 of the ring might besecured in the attaching part by other means than screw threads, butthis mode of securing the attaching device is preferred.

Having thus described my invention, I claim 1. Adevic'e for the purposespecified, comprising a ring composed of a single hollow part or section1, and a single solid section 2, which completes the ring, two rollers 3on said solid section, and means for rigidly securing the respectiveends of the solid section to those of the hollow section, said meanscomprising an end piece which is screwed onto the solid section 2,embraces both externally and internally the end of the hollow section 1,and is secured thereto, substantially as set forth.

2. A device for the purpose specified, comprising a ring composed of amajor hollow section 1, a solid section 2, and attaching devices screwedonto the respective ends of the section 2, said attaching devices havingeach a cylindrical groove engaged by the end of the section 1, whereinit is secured by clenching, and rollers on said part 2.

3. A device for the purpose specified, consisting of a'ring composed ofa tubular portion i or section 1, two attaching devices 4, having ineach a recess which receives the end of the my name, this 22d day ofMarch, 1906 in the tubular section 1, and a circumferential in presenceof two subscribing Witnesses. dentation 6 which secures the partstogether,

- and a solid part or section 2 secured at its re- DICKRAN SARKISIAN 5spective ends in the said attaching devices, Witnesses:

and rollers on said section 2. JOSEPH H. LEWIS,
